1.
A shielded, four-wire cable (e. g. 4 x 1 mm
is required to connect the detector.
2.
Remove the connecting head cap of the detector by
undoing the 4 screws.
3.
Connect the four wires to the terminal of the detector
electronic unit (see Fig. 5-2).
CAUTION
Electrical isolation is only safeguarded when terminal 4
is not connected to terminal 2 of the auxiliary voltage!
4.
Connect the shielding to the EMC cable entry.
6
IMPORTANT
For reasons of EMC the shielding should not be
routed through the case, in order to preserve the
shielding effect!
5.
Replace the connection head cap and screw tightly.
Make sure that the sealing is in the correct position.
